I took this photo, looking north at Brighton Junction near Archer and Western Avenues, on Chicago's near southwest side. Big changes are in the works for this old manual steam era interchange junction. To the far left can be seen a brand new large signal relay box. There is talk circulating amongst the local railfan community, that Brighton Junction is to be eventually "phased out", and the operators shack and old semaphore signals will be removed after all these years. All signalling will be automated. There was even evidence that day, of a new overhead signal bridge foundation under construction. You may want to take some photos while you can.
